DotNet Example: Send an email
This example is an Xbasic script that sends an email using the .NET System::Net::Mail class. Copy this into a new Xbasic module or desktop script, fill in your parameters, and test it from your application.
In addition to built-in server-side and client-side actions for sending emails as part of a business process, the .NET System::Net::Mail class can be used to script the creation and sending of emails using Xbasic.
This example can be transformed into a customized Send_Email function for an application that accepts the recipient, subject, and body as parameters to the method. Other settings can be declared within the function. Messages can have multiple To, CC, and Bcc recipients specified as a collection of MailAddress objects. Properties and methods of the Mail.MailMessage class can be inspected directly from the Xbasic editor. Alpha Anywhere's auto-complete will display a list of properties an methods as code is written:
A list of properties and methods can also be listed in the interactive window using the ? operator:
dim msg as System::Net::Mail::MailMessage ? msg = PUBLIC Dispose AS System::Void () 'Dispose PUBLIC Equals AS L (obj AS A) 'Equals PUBLIC GetHashCode AS N () 'GetHashCode PUBLIC GetType AS System::Type () 'GetType PUBLIC MailMessage() 'Public Constructor PUBLIC STATIC ReferenceEquals AS L (objA AS A, objB AS A) 'ReferenceEquals PUBLIC ToString AS C () 'ToString +AlternateViews. +Attachments. +Bcc. Body = "" BodyEncoding = <No data returned> +BodyTransferEncoding. +CC. +DeliveryNotificationOptions. From = <No data returned> +Headers. HeadersEncoding = <No data returned> IsBodyHtml = .F. +Priority. ReplyTo = <No data returned> +ReplyToList. Sender = <No data returned> Subject = "" SubjectEncoding = <No data returned> +To.
If you want display names with your email addresses (e.g. "Mortimer Snerd <firstname.lastname@example.org>"), use one of the long MailAddress constructors described here.
msg.From = new System::Net::Mail::MailAddress("email@example.com","Mortimer Snerd")
You can also use a long constructor for the MailMessage object to initialize it using two MailAddress objects corresponding to the From and To addresses, e.g.
dim FromAddr as System::Net::Mail::MailAddress = \ new System::Net::Mail::MailAddress("firstname.lastname@example.org","Charlie McCarthy") dim ToAddr as System::Net::Mail::MailAddress = \ new System::Net::Mail::MailAddress("email@example.com","Mortimer Snerd") dim Msg as System::Net::Mail::MailMessage = \ new System::Net::Mail::MailMessage(FromAddr ,ToAddr)
In our sample code below we use the simple MailAddress constructor, which does not allow for a display name.
If you want file attachments, uncomment the msg.Attachments.Add line. If you want them sometimes, add a test for a non-zero length for FileAttachment. If you want multiple attachments, add a FOR or FOR EACH loop on an array of attachment names. It would also be good to test for the existence of each file you want to send before attaching it.
This general method for sending email is a good alternative to the various email functions built into Xbasic.
